Our procedure of investigating the equations
(REF ,REF ) in the replica limit \(n\rightarrow 0\)  will follow
the standard pattern suggested by developments in spin glass theory[1]}.
We first seek for the so-called "replica symmetric" solution, and
then investigate its stability depending on \(\gamma \) . When the
replica symmetric solution is found inadequate, it should be replaced
by the hierarchical ("Parisi", or "ultrametric") ansatz for the
matrix elements \(q_{ab}\) , with various levels of replica symmetry
breaking.
